DOOR AND LINTEL FOR SILGS Filed May 4, 1928 ,zzgl 1 I 2a f0.1.; 20l j Patented Mar. 4, 1930 ADOLPH I. ANDERSON, OF ZUMBROTA, MINNESOTA Doon AND LINrEL FOR sILos Application led May 4, 1928.

The object of this invention is to provide a lintel especially designed for a door way of a silo but also useful in other connections,

` and especially to .provide reinforcement for a metallic lintel plate.

` A further object is to provide a combined door frame and lintel with the elementsso assembled that an especially eficient construction results, the elements being rein- 1forced in the special manner indicated be- IVith the foregoing and other objects in View, the invention consists in the novel construction and arrangement of elements l5 described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the invention.

` InV the drawings forming part of this application Figure 1 is a. view'in elevation showing a portion of a wall of a silo, the door way being provided with a frame and lintel constructed in the manner herein disclosed.

Figure 2 is a bottom plan view of the lintel per se.

Figure 3 is a longitudinal section thru the lintel plate and the reinforcement therefor.

Figure 4L is a section on line 4 4 of Figure 3, thru the lintel plate and its reinforcement.

Figure 5 is a horizontal section thru one side portion of the door frame, showing also a portion of the wall to whichthe tile elel mentsof the frame are anchored and a por tion of the door, also in section.`

In Figure 1 a portion of the wall of the silo or the like is designated 10. and a door `way is equipped with the lintel andframe to be described, and with a 'threshold or the like designated 11, the latter being cement or concrete if desired.

The lintel comprises a metallic plate 12, a body of concrete reinforcement 13 which is itself reinforced, or may be so reinforced, by means of wire fabric 14 to be embedded therein.

The body of reinforcement is retained by bolts 15 havingtheir heads countersunk at '16 and being equipped with nuts 17 which are Serial No. 275,110.

countersunk in the body of concrete-or in any event a portion of these bolts 15 may be so inserted, although the end bolts may be connected directly with the structure of the wall l0. The frame consists of hollow tiling shown at 18 in Figure 5, where it appears in horizontal section and shown in elevation in Figure 1. The tiling may have extending vertically therethru a rod 19 which is to be anchored by means of a wire or U member 20 to the wall 10. The tiles are preferably chamfered as shown at 20, forming a door jamb, a portion of the door appearing in section in Figure 5 and being designated 21.

In Figure 1 it will be observed that the ends of the lintel plate 12 extend into the wall structure, and the body of concrete rests or may rest upon the tiling 18 and may also extend laterally therefrom and into the wall structure, if so desired.

Having described the invention what is claimed is z- 1. A lintel, comprising a thin metallic plate element and a relatively heavy body of reinforced concrete mechanically connected therewith, the plate being proportioned for support in a wall structure laterally of a frame for an opening therein.

2. A lintel, comprising a thin metallic plate, securing devices depending therefrom, and a relatively heavv body of plastic material in which said devices are embedded, the plate being proportioned for support in a wall structure laterally of a frame for an opening therein.

3. In a construction of the class described, a door frame comprising a hollow reinforced structure, means for anchoring said structure to a wall at the edges of a door way, and a lintel comprising a plate extending across the upper ends of the frame, and laterally therefrom into a wall structure, said lintel including a reinforcement depending from the same and supported upon the upper portions of the frame and jointly by the latter and by the plate and wall.

In testimony whereof I affix my signature.
